Air Quality

Air quality is key to the health of humans and ecosystems. The Environment Act (1995) requires borough and district councils to identify Air Quality Management Areas (AQMAs) where current or future air quality is unlikely to meet national air quality objectives, and to develop Air Quality Action Plans to tackle poor air quality in these areas.

The county council's Air Quality Strategy has been superseded by the new Low Emissions Transport Strategy which replaces both the older Climate Change Strategy and the Air Quality Strategy.

The Low Emissions Transport Strategy outlines how we work to address air quality.
